Abstract
From Monodonta labio a mixture of aminoalkylphosphonyl cerebrosides was isolated in a yield of 1·0% of the total complex lipids. The aminoalkylphosphonyl cerebrosides were found to be composed of a major portion of 1-O-[6′-O-(N-methylalaminoethylphosphonyl]galactopyranosyl]ceramide and a minor portion of 1-O-[6′-O-(aminoethylphosphonyl]galactopyranosyl]ceramide. Palmitic (49·7%) and 2-hydroxy palmitic (12·2%) acids were the main fatty acid constituents and a small amount of oleic acid was also detected. The long chain bases had a characteristic pattern with 16–22 carbon chain lengths, and were classified into four groups: normal dihydroxy monounsaturated bases (40·6%), branched dihydroxy monounsaturated bases (34·0%), dihydroxy diunsaturated bases (22·0%), and trihydroxy bases (2·2%). Among them dihydroxy 18 : 1 and 18 : 2 and branched 19 : 1 bases were predominant.This publication has 1 reference indexed in Scilit:
